What is the best video game you have ever played?

[Falkirion]

For me on the PS1 my favorite without a doubt is final fantasy 9. Played plenty of good games in my lifetime.
Zelda Ocarina-Majoras-Wind waker are brilliant.
Vampire Slayer mod for HL1. That was always fun with friends at around 1am at a LAN party. Lights off, headphones on, screams and laughter ensued.
Heaps of other games out there that I love

I think the best flight sim was Janes WW ll fighters now that I got it all modded out and it will run on a 20 dollar machine all day long.

SH 4 is a top notch subsim and SH 3 with the S-boote mod is sway cool.
Played Metal of Honor series and Brothers in Arms, Aces High 2 online was something else.

I think that I spent more time with Aces of the Deep, X-Com UFO Defense and Harpoon 2 than anything else since.

I like games that give me the most freedom to play how I want, and open worlds in which to do so. So for me, my favourites in no particular order:

SH3 or 4
Fallout 3/ New Vegas
FSX
Arma 2

I'm a S.T.A.L.K.E.R. SOC Nut. (Planning on getting a "marked by the zone" tattoo sometime in the near future)
I miss playing that game. THe only reason I don't is because my poor computer is hooked up in the attic, which was 115 degrees Fahrenheit last I checked (Excellent for immersion when playing GTR 2 though, race cars don't have air condidioning!)

I loved playing Metro 2033. Test Drive Unlimited, GTR 2 with the Power and Glory mod, and GTR 2 with the ALMS mod.
